阶状断面和组合锚杆在开双切眼中的研究应用

Research and Application of Scalariform Cross-section and Combination Bolts in Opening Double-cut Eyes

针对仰采综采工作面开双切眼支护和安装支架存在的问题,采用组合锚杆联合支护和阶梯状断面,解决了大断面仰采倾斜工作面顶板支护和安装支架的技术难题,安全生产得到了有效的保证。

According to the problems of upward and mechanized mining face double-cut eyes support and mounting bracket,this paper used the combination bolts combined support and scalariform cross-section,which solved technical problems in large section upward sloping mining face roof support and mounting bracket,so the safety production has been effectively guaranteed.
